Compile warning and cannot run

[lystormenvoy]

gcc version: gcc (GCC) 12.3.1 (openEuler 12.3.1-30.oe2403)
source: 2.6.0-stable in github's release

I compile with these warning but it seems can finish the compile.
I copy the uftpd.cfg to /etc
I run uFTP it print Hello uFTP server v2.6.0 stable starting.. then I use ps -ef | grep uFTP and can't see process.

Compiler: gcc
Output Directory: ./build/
CGI FILES: start uFTP end
Clean ok
